Eric, one battery or multiples, thats your call. I've always found one good battery and a good 30amp converter does the trick. If you really want the top of the line, Mil-spec, sealed (AGM) Navy tested, glass mat, can't beat them with a stick, 5 yr and, yes, 10 yr warranty batterys, go to : www.dcbattery.com/index.html

These batterys make all other batterys look like toys for tiny trucks. I didn't check the prices, but let me assure you, they are much like Doug's VHMB. They like to be treated rough, but they will NOT explode. 10 year Warranty????? Have Fun

I just came from Wally World. They have deep cycle 105 amp hour batteries for $55.00

The question is: Do I buy two and parallel them? Would that be a good idea or not??
